We present a theoretical analysis of extraordinary optical transmission phenomena in periodic arrays of subwavelength apertures incorporating optically-pumped gain media. We show that, as a consequence of the strong spatial hole-burning effects displayed by the considered structures, three separate regimes of operation arise: the system can behave as an absorber, an optical amplifier or a laser, depending on the value of the pump intensity.
